IMPROVEMENT IN HAY ELEVATORS.

ro ALL wnonir Marconcnanf i Be it known that I, E. C. GREEN, cf Plainfield, in the county of Hendricks, and State of Indiana,'have invented a new and useful Improvement in I-Iay Loader; and I do hereby declare that the following is a full, clear, and exact description thereof, which'will enable-others skilled in the art to make and use the saine, refer ence beingV had to the accompanying drawings, forming part of this specication, in which- Figure l is a perspective side view of my hay-loading apparatus.

Figure 2, a transverse vertical section of the same.

Similar letters ol' reference indicate like parts. v

The object of this invention is to load hay orcorn-t'odder upon wagons, either from the shock or the windrow in the field; and it consists yin a light, portable frame to be set upon the running gear of a wagon,connected with which frame is a hollow central post enclosing a sliding and revolving upright, on the top of`whichis a cross-bar, forming a kind of crane or derrick for swinging around to take upland .drop abundle of hay on opposite sides of a wagon, as desired, and rising higher as the hay is loaded by means of a horse hay-fork worked by a rope-and pulleys. i i

In the centre ofthe frame or bed A A, stands an upright hollow post, B, made by preference of inch plank about seven inches square and six and a half feet long, the -foot of which is stepped into' a cross-plate, C; it is Supported also by braces an au. On the upper end of the post B is a cap, b, through the middle of which passes a round standard, D, the lower end of which` reaches down to the bottom of the square posil I3, within which it turns around and slides up and down like apiston, by means of a suitable head fitting in the inside of the hollow post B. The centre standard D projects several feet above the top of-tlie post B, and on its upper end is fastened a cross-arm, E, projecting on one side about four feet and a half,- and on the other side about one foot and a half; it isvsupported at the bottom by 'one or more braces, c. On the long end of the cross-arm E are placed two vertical pulleys, d al, one at the extremity and` the other near its connection with the centre standard D. The standard. D has a hole bored through it from end to end for receiving a hoisting rope, c, which pass-es over thev pulleys CZ d, and down -through vthe hole to the under side'ot` the cross-plate C, where it passes around another Vpulley,j', and, running along the ground at right angles to the frame A, is hitched to a horse Vfor loading the hay. On the other end of the rope eisattached -a horse hay-rake, Gr, formed of the curved prongs gg, which are closed and opened by means of two strands on the end of the rope, which pass'over two small pulleys, 7L h, fixed in the ends of a doublestationary fork, t', to which the- .prongs gg are pivote'd, `the two -strands of rope being fastened to the projecting heads 7c 7c, of the prongs gg, to close them when the rope e is pulled.

Just forward of the centre post B, a round slide-bar, AF, lies'crosswise ou the bed A, which is moved in and out, as desired for loading, on the outer end of which vbar is a pulley, s, over which the rope c passes to bring the draught near the ground when the hay is to be taken from the windrow and drawn to the wagon. A light spring, Z, on the end of the slide-roller F holds the rope against the side of the pulley while the hay is drawn from the windrow; the spring becomes inoperative and the-rope is'releascd from the pulley in order to hoist the hay upon the wagon by giving the slide-roller F a half turn upward, which is done by means of arope, m, fastened to 'the bar and connected with' a crank or lever, n, at the rear end ofthe frame. .,A. spring,p, connected with the bar F, by the rod g, turns it back again in place, when the rope m is released. i

The operation of the apparatus is obvious and requires no further' explanation. The centre standard D is raised as the hay is loaded on thc wagon, and is held in place by a spring-catch placed on the cap b, and when the load is completed it is lowered 4so that the wagon can drive into the barn with the load of hay.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-' 1. I claim the hoisting lapparatus herein described, in combination with the wagon-bed A, arranged and operating substantially asand for the purposes herein specified. v

2. I claim the hollow'centre post B, enclosing the hollow centre standard D, with itscross-arm E, and

pulleys dd, in combination with .the slide-roller F, with its pulley s, andspring Z, connected 'with the horse rake G, and operated bythe rope c,- eonstructed, arranged, and operating together substantially as and for thcv purposes'herei'n described.

3i I claim the crank'n, yin combination with thc sliileu'ollcrF, and the spring p, Constructed and arranged substantially as and for-the purposes set forth.
